It looks like our customizations are not working properly, as
ess-indent-level is customizable but is not being remembered.  I will
investigate, but in the meantime, this should work for you:

put this in .emacs and restart Emacs:

(defun myindent-ess-hook ()
  (setq ess-indent-level 4))

(add-hook 'ess-mode-hook 'myindent-ess-hook)
